Display controlling apparatus, display controlling method, and program

Abstract

Disclosed herein is a display controlling apparatus, including a light source controlling section adapted to generate a light emitting signal which defines a luminance of a light source based on an input image signal representative of an image and transmit the generated light emission signal to the light source; a gradation conversion section adapted to convert a gradation of the input image signal; and a transmission factor controlling section adapted to generate, based on the light emission signal and a conversion image signal which is an image signal having a gradation converted from that of the input image signal, a transmission controlling signal which defines a transmission factor of light emitted from the light source through a display panel and transmit the generated transmission controlling signal to the display panel.

1 . A display controlling apparatus, comprising:
 a light source controlling section adapted to generate a light emitting signal which defines a luminance of a light source based on an input image signal representative of an image and transmit the generated light emission signal to the light source;   a gradation conversion section adapted to convert a gradation of the input image signal; and   a transmission factor controlling section adapted to generate, based on the light emission signal and a conversion image signal which is an image signal having a gradation converted from that of the input image signal, a transmission controlling signal which defines a transmission factor of light emitted from the light source through a display panel and transmit the generated transmission controlling signal to the display panel.   
     
     
         2 . The display controlling apparatus according to  claim 1 , further comprising:
 a decision section adapted to decide based on the input image signal whether or not the gradation of the input image signal should be converted; wherein   said decision section transmits, when said decision section decides that the gradation of the input image signal should be converted, the input image signal to said gradation conversion section whereas, when said decision section does not decide that the gradation of the input image signal should be converted, said decision section transmits the input image signal to said transmission factor controlling section, and   said transmission factor controlling section generates the transmission controlling signal based on the light emission signal and one of the input image signal and the conversion image signal.   
     
     
         3 . The display controlling apparatus according to  claim 1 , further comprising:
 a light source adapted to emit light in response to the light emission signal transmitted thereto; and   a display panel adapted to adjust the transmission factor in response to the transmission controlling signal to be transmitted to display an image on a display screen thereof.   
     
     
         4 . A display controlling method, comprising:
 generating a light emitting signal which defines a luminance of a light source based on an input image signal representative of an image and transmitting the generated light emission signal to the light source;   converting a gradation of the input image signal; and   generating, based on the light emission signal and a conversion image signal which is an image signal having a gradation converted from that of the input image signal, a transmission controlling signal which defines a transmission factor of light emitted from the light source through a display panel and transmitting the generated transmission controlling signal to the display panel.   
     
     
         5 . A program causing a computer to function as:
 a light source controller generating a light emitting signal which defines a luminance of a light source based on an input image signal representative of an image and transmitting the generated light emission signal to the light source;   a gradation converter converting a gradation of the input image signal; and   a transmission factor controller generating, based on the light emission signal and a conversion image signal which is an image signal having a gradation converted from that of the input image signal, a transmission controlling signal which defines a transmission factor of light emitted from the light source through a display panel and transmitting the generated transmission controlling signal to the display panel.
